Like others, I am a bit surprised that the screen is passed on to non insured purchasers, especially as we were reassured on the forum that this wouldn't happen as it would involve too much work to change the screen in the testing stage.
That has not been confirmed.
On the note of the delay however, 11 working days in testing is a VERY long time, I'd probably consider getting in touch with them regardless to see what's up, most likely something failed and was replaced but 11 working days is still a long time.
